Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of medium levels in chambers is used to adapt to different body contours and weights, then adaptability to individual users is improved, but ease of operation deteriorates due to the inconvenience of manual adjustment
Solution Approach 1:
The control unit automatically detects the user's body contour and weight through pressure sensors and independently adjusts the medium levels in the chambers without requiring manual intervention. The system serves itself by using the pressure detection data to autonomously optimize the support characteristics for each user.
Solution Approach 2:
The pressure detection unit continuously monitors the pressures in the chambers and provides feedback to the control unit, which then adjusts the medium levels accordingly. This closed-loop feedback system ensures that the sleep system automatically adapts to the user's body characteristics and maintains optimal support conditions.
2Adaptability or versatility
If manual adjustment is required for changes in user stature, then adaptability to different users is improved, but loss of time increases due to repeated adjustment needs
Solution Approach 1:
The system performs preliminary detection of the user's body characteristics upon each use and automatically pre-adjusts the chamber pressures before the user settles into the sleep position. This eliminates the need for time-consuming manual adjustments when users change or when body characteristics vary.
Solution Approach 2:
The control unit independently handles all adjustment operations based on pressure detection data, freeing the user from any adjustment tasks. The system automatically adapts to different users and changing body statures without requiring user intervention or time investment.
3Ease of operation
If pressure detection unit and automatic control system are integrated, then ease of operation is improved by eliminating manual adjustment, but device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it controls the filling device, monitors pressure levels, detects user body characteristics, and automatically adjusts chamber pressures. By consolidating these diverse functions into a single multi-functional control unit, the patent manages complexity while achieving automatic operation.
Solution Approach 2:
The pressure detection unit and control system are integrated into a unified automatic control mechanism that combines sensing, processing, and actuation functions. This merging of components streamlines the system architecture and reduces operational complexity despite the advanced automation capabilities.
4Force
If chambers are filled with medium for support, then support force is improved, but reliability deteriorates due to potential air leaks and medium loss
Solution Approach 1:
The pressure detection unit continuously monitors the pressures in the chambers and provides real-time feedback to the control unit. When pressure deviations occur due to leaks or medium loss, the system automatically detects and corrects these deviations by adjusting the medium levels, thereby maintaining consistent support force and reliability.
Solution Approach 2:
The automatic control system proactively monitors and maintains optimal pressure levels in the chambers, compensating for potential leaks or medium loss before they significantly impact support reliability. This continuous monitoring and adjustment ensures consistent performance despite potential reliability issues.
